What Is a Pip in Gold (XAUUSD) and How to Calculate It
A pip on XAUUSD (gold) is defined the same way in price terms across almost every broker, but the contract size behind it is not always 100 ounces the way many traders assume. Getting that one number wrong is the single most common way traders miscalculate their gold position size, so let me walk through exactly how to check it properly before you calculate anything.
Gold’s Pip Size Is 0.01
Gold is quoted to two decimal places, for example 2,341.55. A move from 2,341.55 to 2,341.56 is 1 pip. That part is essentially fixed across the industry — what varies broker to broker is the contract size, and that’s where the real risk of a wrong calculation lives.
Check Your Broker’s Contract Size
Here’s how to find the real number on a typical MT4/MT5 platform:
- Go to Market Watch and find XAUUSD.
- Right-click on XAUUSD and select Specification from the menu.
- Look for the Contract size field in the window that opens.
Many brokers set the contract size for XAUUSD at 100 ounces — meaning 1 standard lot equals 100 ounces of gold. That’s very different from a forex pair like GBP/USD, where 1 standard lot is 100,000 units of currency (see What Is Lot Size in Forex? for the full breakdown). Other brokers, though, run a 10-ounce contract size instead, or even other variants entirely. There is no single universal number here, which is exactly why checking the Specification window yourself, every time you switch brokers, matters more for gold than it does for most forex pairs.
Calculating Pip Value on Gold
Once you know the real contract size, pip value follows the same formula as any other instrument (the same one broken down step by step in Profit Per Pip): pip size × contract size × lot size, converted to your deposit currency if needed.
With a 100-ounce contract size and a USD deposit currency, 1 standard lot of XAUUSD moves $1 per pip (0.01 pip size × 100 ounces = $1). A 0.10 lot moves $0.10 per pip, and a 0.01 lot moves $0.01 per pip — the same scaling relationship as any forex pair, just with gold’s own contract size feeding into it instead of 100,000 units.
Now picture the broker with a 10-ounce contract size instead of 100. Under that setup, the exact same 1.00 lot only moves $0.10 per pip — a tenfold difference in pip value for an identical “1.00 lot” order, purely because the underlying contract size is different. This is worth sitting with for a second: the word “lot” on its own tells you nothing about actual dollar risk until you know the contract size behind it.
Worked Example: A Trap Worth Knowing
Say a trader assumes their broker uses the common 100-ounce contract size, and calculates a lot size of 0.50 to risk $200 over a 40-pip stop ($200 ÷ (40 × $1 × 0.50) — working backward, they expect $1 per pip per full lot, so 0.50 lots should risk exactly $200 over 40 pips). If that broker actually runs a 10-ounce contract instead, the real pip value on 0.50 lots is only $0.05, not $0.50 — meaning the actual risk on that trade is just $20, one tenth of what was planned. That specific mix-up isn’t dangerous by itself (it just means the trade was accidentally under-risked), but the same error running the other direction — assuming a smaller contract size when the real one is larger — produces a trade risking ten times more than intended, which is a very different problem.
Deposit Currency Adds Another Layer
Gold is quoted in USD regardless of your account’s currency, so if your account is denominated in EUR, that pip value needs converting through the current EUR/USD rate. At an EUR/USD rate of 1.0850, a $1 USD pip value converts to roughly €0.92 per pip (dividing $1 by 1.0850). The pip is still 0.01 in price terms no matter what currency your account holds — what changes is purely what that pip is worth once translated into your own account currency, and that conversion moves slightly as the EUR/USD rate itself moves.
Putting It Into a Full Position-Size Calculation
Once you know the real pip value, sizing a gold trade uses the same formula as any other instrument. Say your account holds $12,000 and you’re risking 1% ($120) on a trade with a 35-pip stop. With a $1-per-pip pip value on a standard lot (the 100-ounce contract-size scenario):
Lot Size = $120 ÷ (35 × $1) = 3.43 lots
Now run the identical calculation assuming the broker actually uses a 10-ounce contract size, where pip value is $0.10 instead of $1:
Lot Size = $120 ÷ (35 × $0.10) = 34.3 lots
Same account, same risk %, same stop distance — a tenfold difference in the correct lot size, entirely because of which contract size actually applies. This is exactly why the Specification-window check isn’t an optional extra step; it’s the single input the rest of the calculation depends on most heavily (a calculator with real gold examples across USD, EUR and gold-denominated accounts covers this same conversion in more depth).
Why Gold’s Stop Distances Tend to Be Wider
Gold typically moves in larger absolute pip counts per session than a major forex pair, simply because of how it’s priced and how actively it’s traded around economic data and risk-sentiment shifts. A stop loss that would be unusually wide on EUR/USD (60-80 pips) is often a fairly normal distance on gold. This matters for position sizing specifically because a wider stop, combined with a miscalculated pip value, compounds into a bigger dollar error than the same mistake would produce on a tighter-ranging instrument — one more reason to get the contract-size check right before sizing a gold position, rather than after.
Why This Trips People Up Specifically With Gold
Traders coming from forex pairs are used to one fairly consistent contract-size convention (100,000 units per standard lot) holding steady across brokers, so they carry that same assumption over to gold without checking. Gold breaks that assumption in a way most forex pairs don’t, and because gold also tends to move in larger absolute price swings than a typical forex pair, an incorrect pip-value assumption on gold usually produces a bigger dollar-sized mistake than the same kind of error would on, say, EUR/USD.
There’s also a simple reason brokers don’t standardize this the way forex majors are standardized: gold isn’t a currency pair being quoted against another currency in the same way EUR/USD is. It’s a commodity CFD, and each broker builds its own contract specification for commodity products independently, often influenced by how the underlying futures or spot market they’re hedging against is itself structured. The same broker-specific variance shows up again with synthetic indices, a completely different asset class with the identical underlying problem. That’s the honest, unglamorous reason for the variation — it isn’t an oversight, it’s just a product category with less industry-wide standardization behind it than forex has.
Frequently Asked Questions
Is gold’s pip size always 0.01?
Yes, virtually every broker quotes gold to two decimal places, so 0.01 is the pip size across the board. What varies between brokers is the contract size, not the pip size itself.
Why is my pip value different from what a forex calculator shows?
Because gold’s contract size (100 ounces on many brokers, though not all) is nowhere near a forex pair’s 100,000-unit standard lot. Applying a forex-style assumption to gold gives a wrong answer, often by a large margin.
Does the deposit currency change the pip size?
No, the pip size in price terms stays 0.01 regardless of your account currency. What changes is the dollar (or euro, or whatever currency) value of that pip, since it needs converting into your own account currency at the current exchange rate.
Does silver work the same way as gold?
The same principle applies — check your specific broker’s contract size for XAGUSD rather than assuming it matches gold’s. Silver contract sizes and pip conventions vary between brokers just as much as gold’s do, sometimes more.
